## Job description

🚀 We’re hiring at Supersonik!

Finance Operations Associate

## About the role

We are looking for a highly autonomous, proactive person to take ownership of our day-to-day accounting operations, from supplier invoices and payments to customer invoicing. You will be the go-to person for keeping the finance back-office accurate, up to date, and running without needing to be chased. You will also cover office management and general admin tasks.

This is a role for someone who spots what needs to be done and does it, flags issues before they become problems, and improves processes along the way. You will work closely with the Finance and Operations team, in a fast-paced startup environment with real scope for ownership.

## Key Responsibilities

Accounts Payable & Supplier Management (core focus)

- Own the supplier follow-up process: chase, collect, and validate invoices proactively, with no reminders needed.
- Manage the full AP cycle: invoice collection, supervise registration, approval workflow, and payment preparation and execution.
- Prepare and execute supplier payment runs, ensuring payments are accurate and on time.
- Reconcile supplier statements and resolve discrepancies.
- Review supplier and customer invoices for tax compliance (tax IDs, VAT, withholdings) and support the preparation of periodic tax filings together with our external advisors

Accounts Receivable & Customer Invoicing

- Issue customer invoices accurately and on time.
- Track collections and follow up on overdue payments.
- Keep customer data, contracts, and billing information up to date and consistent.

Accounting Support

- Ensure complete, organized documentation and filing of all financial transactions.
- Support bank reconciliations and expense tracking.
- Coordinate with external accountants and auditors, and provide the information they need on time.
- Support month-end close by preparing and reviewing supporting documentation.

Office Management & Administration

- Oversee day-to-day office operations and administrative processes
- Manage internal documentation, contracts, and records
- Coordinate vendor relationships (suppliers, service providers, etc.)
- Support basic HR/admin processes (onboarding logistics, documentation, etc.)
- Ensure proper organization of company files and tools (Drive, Notion, etc.)
- Handle general administrative tasks to support team efficiency

Who we're looking for

- Autonomous and proactive: you take ownership, anticipate needs, and follow tasks through to completion without close supervision.
- 2-5 years of experience in accounting, accounts payable/receivable, or finance support roles
- Hands-on experience with supplier follow-up, supplier payments, and customer invoicing
- Solid grounding in accounting fundamentals
- Comfortable working with financial and administrative processes
- Native Spanish and at least advanced English required, for both internal and external communications
- Proficiency in Excel and general office tools
- Strong organization and attention to detail, with the ability to manage multiple priorities and deadlines independently

## Nice to have

- Hands-on experience with Odoo and Ramp (or similar ERP and spend management tools)
- Experience in a startup or scale-up environment, ideally in SaaS or tech

Recruiting process:

- As part of our selection process, shortlisted candidates will complete a live practical assessment to demonstrate their experience

## About Supersonik

## Company Overview
- **One-liner**: Supersonik deploys AI agents that deliver instant, personalized, and interactive product demos 24/7 for B2B SaaS companies.
- **Entity Type**: Private (Seed stage – $5M seed round led by Andreessen Horowitz)
- **Headquarters**: Barcelona, Catalonia, Spain (also has a San Francisco office)
- **Founded**: 2025 (first funding round in March 2025)
- **Founders**: Dani Carmona (Co-Founder & CEO), Pol Ruiz Farre (Co-Founder & CTO), Joaquim Lecha (Co-Founder)

## Core Business
- **Primary industry**: AI-powered sales enablement / conversational AI for SaaS
- **Target customers**: B2B SaaS companies of all sizes (SMB to Enterprise) looking to accelerate sales cycles
- **Mission**: Replace outdated, manual demo processes with smart, dynamic AI-driven experiences that let prospects get a live, personalized demo instantly

## Products & Services
- **Supersonik AI Agent**: An AI that logs into a company's real product, navigates it in real time, and conducts a video-call-like demo. It captures user context, personalizes the flow, and guides prospects to a call to action (e.g., free trial, booking). Available as embedded widget on website or as a shareable link. Supports 70+ languages, runs thousands of concurrent sessions with ultra-low latency, and is SOC 2 Type II and GDPR compliant. [supersonik.ai](https://supersonik.ai/product)

## Market Standing
- **Valuation**: Not disclosed (seed round of $5M implies a post-money valuation likely under $30M, but not publicly confirmed)
- **Key Metric**: Total funding of $4.9M (Seed round $4.9M in Oct 2025, plus an earlier Pre-Seed round in Mar 2025) [linkedin.com](https://linkedin.com/company/supersonik-ai)
- **Notable Investors/Partners**: Lead investor: Andreessen Horowitz (a16z). Angel investors from Google, DeepMind, and Salesforce. Also reportedly used by 200+ Salesforce SDRs across Americas, LATAM, and EMEA. [supersonik.ai/blog/seed-round-announcement](https://supersonik.ai/blog/seed-round-announcement)
- **Growth Signals**: 25 employees with +12.5% monthly headcount growth; 5 active job postings (as of Sept 2026); quarterly job posting growth of +150%. Engaged with "thousands of businesses" per website. [linkedin.com](https://linkedin.com/company/supersonik-ai)

## Competitive Advantages
- **Real‑time product navigation**: Unlike static demo videos or chatbots, the AI actually drives the live product interface, creating a realistic, interactive experience
- **Hyper‑personalization**: Adapts the demo on the fly based on user details (name, role, context) gathered at the start of each call
- **Extreme scalability**: Can run thousands of simultaneous sessions without degradation, with industry‑lowest latency and multi‑region servers
- **Enterprise‑grade security**: SOC 2 Type II and GDPR compliant, trusted by large enterprises like Salesforce
- **Multi‑language support**: 70+ languages out of the box, removing language barriers to global sales

## Strategic Focus
- **Current priorities**: Deepening integrations with CRM and data sources (e.g., Salesforce), scaling the GTM organization (hiring Strategic Account Executives, Sales Operations Lead, Head of AI Delivery Operations), and expanding use cases beyond demos into onboarding, support, and the entire customer journey. [supersonik.ai/blog/seed-round-announcement](https://supersonik.ai/blog/seed-round-announcement)
- **Growth direction**: Becoming the "Live Product Experience Platform" that serves every stage of the customer lifecycle, not just pre-sales.

## Why Work Here
- **Culture**: Described as "fast-paced, agentic AI startup" where early‑career employees get "real ownership, steep growth." The team is distributed across 5 countries (Spain, US, UK, Ireland, Germany), with an office hub in Barcelona and a smaller presence in San Francisco. [linkedin.com](https://linkedin.com/company/supersonik-ai)
- **Remote/Hybrid**: Not explicitly stated, but the distributed workforce and two offices suggest a hybrid or remote‑friendly culture, especially for engineering and GTM roles.
- **Engineering Culture**: ~33% of staff are in technical roles (9 out of 25). The technical stack involves AI, real‑time systems, and security compliance, offering engineers exposure to cutting‑edge agentic AI.
- **Notable Perks**: Being backed by a16z provides strong runway and network. Employees get to work on a product that is already being used by a major enterprise (Salesforce). The company is still small (25 people) – offering strong ownership and impact.
- **Hiring Activity**: 5 open positions as of Sept 2026, including sales, operations, and AI delivery roles. [linkedin.com](https://linkedin.com/company/supersonik-ai)
